Default Getting rid of the Purge Control Solenoid

I busted the purge control solenoid on my scoob a while back, and have been getting an associated CEL ever since. The obvious answer is to just replace is, but $100 for something that doesn't make the car go faster, stop better or corner more impressively seems like a waste of my tuning dollars. Does anyone have an idea on how to delete the thing while keeping the evaporative emissions system CEL from reappearing, short of deleting the code?

Thanks in advance!

remove and delete, then watch the code come back. if you remove the purge valve, they light will come right back on once the evap system runs any kind of test and/or trys to purge the system. the only way to bypass it may be for a tuner to do so.

i bought my purge valve used from a member on here, 20 bucks.

Evap systems are VERY complicated and the OEM engineers build in multiple self-diagnostic tests to verify that the system is working. This is because a large portion of HC emissions are produced by gasoline vapors. It is one of the main reasons why returnless fuel systems exist, and why fuel pumps are duty controlled.

Eliminate the code with a reflash. You can't just pull it out on an OBD II car.

2 dozen times? I am assuming you do it temporarily and then hook it all back up.

But, maybe not. So I am going to try this tomorrow... except permanently. This system is definitely the source of my vacuum leak and I don't have the money/motivation to fix it. I hate all the vacuum lines clogging up my engine bay anyways.

I'll update this thread with my results over time.

Yea that's the one. Has a little plastic "F" that lines hook up to. The ECU won't throw codes at you if the valve is plugged into the harness and the lines capped off.

Yes 2 dozen. I own a shop and do engine builds all day long (can't say shop name for fear of Nazi mods)

Remove the UFO and purge solenoid garbage and just delete the code. No one will ever know :P
